More about RF Modulators

Modulation in its most basic definition is the mixing of two sinusoidal signals. The RF modulator takes an input signal and outputs a modulated signal to be transmitted as a video channel to any number of connected TVs. RF Modulators are used to distribute video in widely diverse installations, including stadiums, arenas, office buildings, college campuses, houses of worship, sports bars, and restaurants

Full Description & Specifications

The dual-channel QMOD-SDI 1.5, with SDI and Component inputs, sets a new standard for sports, motion and digital signage encoding. Dual hardware scalers accept content up to 3G 1080p, shapes signage for edge-to-edge presentation, and compensates for non-broadcast and PAL refresh rates. Able to deliver two HD programs in one channel, the QMOD-SDI 1.5 can also output the content as a Multicast or Unicast IPTV stream. Options include dual-language SAP audio, easy front-panel setup and alternate audio and NTSC video inputs. Web setup, monitoring, and firmware updates are available via USB and Ethernet ports. Two-across mounting offers up to four programs per rack space, with the ability to mix models to handle HDMI, SDI, Component, RGBHV and NTSC video sources.
